Name: Juniperus osteosperma / Pleuraphis jamesii Woodland Reference: Western Ecology Working Group of... Description: This woodland association occurs on valley floors, ridges, and benches in northwestern Colorado and eastern Utah. Sites have gentle to moderate slopes (2-16%), occur between 1341 and 1860 m elevation, and may be oriented to any aspect. The unvegetated surface has high cover of litter and low exposure of bare soil. Soils are well-drained sands, sandy clays, or clay loams derived from shales, sandstones, talus, eolian sands or alluvium. Stands occur in relatively small patches, often in a mosaic with other pinyon-juniper / grass understory woodland types. Total vegetation cover rarely exceeds 60%. The tree canopy consists of <i>Juniperus osteosperma</i> with between 5 and 40% cover. <i>Pinus edulis</i> is generally absent. Scattered shrubs, such as <i>Artemisia tridentata ssp. wyomingensis, Atriplex canescens, Ephedra viridis, Chrysothamnus viscidiflorus, Gutierrezia sarothrae</i>, and <i>Opuntia polyacantha</i>, may be present, but there is no developed shrub layer. The herbaceous stratum is sparse to moderately dense and is dominated by graminoids. <i>Pleuraphis jamesii</i> is dominant to codominant and is generally accompanied by other grasses such as <i>Achnatherum hymenoides, Bouteloua gracilis</i>, or <i>Hesperostipa comata</i>. Forbs are sparse in cover and inconsistent in composition among sites. Biological soil crusts may be well-developed in areas that are protected from grazing.  Accession Code: VB.CC.31988.CEGL002362 Plot-observations of this Community Concept: 0
